Do you find the Portal useful? We’re asking you to please take a minute today to keep our work going.
This year we added 1.2 million pages of material to the Portal and we need your investment to continue growing.
We’re only $100,000 away from meeting our year-end goals for the Challenge Grant we received from the National Endowment for the Humanities.
During our spring appeal, the average donor gave $30, but if even half the people who use the Portal this month give $5,
we’d meet our entire goal to raise matching funds for the endowment immediately.
The Portal connects people to the past, and your support will ensure its future.
